Application filed January 15,1925. S.eria1 No. 2 ,698.' I

double plunger pumps.

It has as its object. the provision of a simple times.

The pump selected for illustration has a base 1 and standards 2 in which are ournals for the several shafts. Around the standards, and covering them at the top, sides and back, is a hood or cover 3, which rests on the base.)

The base will have any suitable trap or basin for oil from which it is to he pumped to the top of the frame;

The guide rods for the pump rod cross heads are located at 41, and the ."cross heads On the shaft], which may be a rigid shaft, is'the top rocker having a long jourmil 8 on the shaft, and has arms 9 and 10.

The arm lO is connected as desiredto one of the, cross heads, and the arm 9 has'a slideway 11 therein. On'the shaft 12 is a like 1 rocker having arm13 connected to the other, cross head, and the arm 14, having a slideway 15 therein: A pair oflarge gears 16, 16, are supportedrotatably in the two side frames, and are connected by an eccentric rod- 17 wh ch carr es, a ournaled slider 18, e

that engages 1n the slideways 11 and 1 5,

top rocker is secured in any suitable way, an oil pan 21. i

This pan has notches 22 distributed about I its sides and ends, and is keptv filled with oilfrom the delivery pipe 23, located above the pan. Holes are also provided in the corners of the pan for the same purpose.

The movement of the pan is never such as to bring it out of position to receive and retain for distribution theoil pumped from the pipe. That is to say the pan is mounted and made large enough so 'thatit will never rock out of range.

The oil is spilled out through the notches, such a way as to fall in a. shower, bathing the various parts of the pump which havebeen described. The pan is as wide as the parts necessary to be showered, are wide as assembled. The protective casing keeps out dust and dirt, and prevents the oil from splashing. Since, however, the casing or-shell must be left open at the front for the assa e of the rocker arms, and since the lee: age kely to occur through faulty packin could find an entrance into the shell at this point, I provide a special device for preventing such Instead of providing special leak pre venting packing boxes, I provide a baflie de vice which is so mounted as to protect both glands, i. e., where the outer rod passes into the well casing and where the inner rod passes into the outer rod.

The connections of the two rocker arms with the cross heads!) and 6, have not been shown in detail, and any form ofconnection will do, which forward of the axis of the two rods, and far enough from the rods themselves as to. leave'room for a batfie. Mounted fast on the lower gland 80 for the outer pumpv rod is collar 31, to which is screwed the lower. end of a cylindrical bafile plate 32, said baii'le plate being left open at the front for the passage of the cross head otthe outer pump rod.

A sleeve 38 is arranged over the inner pump rod which sleeve has a cross piece 34 thereon, to whichthe sides of the battle are secured as by screws.

The result of this structure is that the baflle does not interfere with the movement of the lower cross head, and does not interfere with the uppercross head, as it is not long enough to reach this cross head in its lowest position; However, the glands f'or'both rods are protected on the side toward the mechanism casing,'so that leaky glands will not result in oil getting into the said casing through the openings necessary for the movement of the rocker arms and connecting rods.

Thusl provide for a lubrication of double plunger pumps of the rocker arm type, in such a way that attention by an engineer is not, necessary. These pumps are often operated. continuously, for long periods of time, and cannot be constantly Watched, and by my invention I have provided for a lubrication feature that is fool-proof to ahigh degree. 7

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

1. In a pump device, a base, a pump rod,

mechanism on said base for operating the mounted on said lever and adapted to be rocked thereby and holes inthe sides of the pan to permit leakage ofoil from the pan to drop it upon the said mechanism, an oil supply: pipe, said pan being so positioned as to receive oil from said pipe.

2. In apump device, a. base, apump rod, mechanism on. said base for operating the rod comprising a rockinglever, an, oil pan mounted on said lever, and adapted to be rocked thereby and holes in the sides of the pan to permit leakage of oil from the pan to drop it upon the said mechanism, an oil supply pipe, said. pan being so positioned as to receive oil. from said pipe, a housing about said mechanism adapted to enclose it except for connections to said' rod, and a bafile for preventing water the housing when leaking about saidpump rod. a

3. In a pump device, the combination of double plunger rods, an operating mechanism, comprising two rocker armsfor operating the rods, and drivingmeans for the rocker arms, one of said rocker arms being mounted above the remainder of the operating mechanism, an oil pan mountedon the upper rocker arm so as. to rock on the same axis therewith, and an oil supply for providing oil to said pan, said pan having openings in its walls, to permit oil to run out as the pan rocks from side to side with said upper rocker arm; j

4,. In a pump device, the combination of double plunger rods, an operating mechanism, comprising two rocker arms for operating the rods, and driving means for the rocker arms, one of said rocker arms'being mounted above the remainder of the operating mechanism, an oil pan mounted on the upper rocker arm so as to rock on the same axis therewith, andan oil supply for providing oil to said pan, said pan having slots in its walls, to permit oil to run out as the pan rocks from side to side with said upper rocker arm, said oil pan being secured to said'rocker arm at its line of support;
